Answer:
5a,b = 17,576,000; 11,232,000
6. 45,697,600; 32,292,000
7. 6,760,000; 3,276,000
8. 118,813,760; 78,936,000

If y varies directly as x and y = 15 when x=-5, find y when x= 7.
A. -21
B. 21
C. 105
D. -35
Answer:
A. -21
Step-by-step explanation:
y varies directly as x
y = kx
----------------------
y = 15 when x = -5
Find k, the constant of variation
15 = k(-5)
Divide both sides by -5
-3 = k
k = -3
------------------------------
y when x= 7
using k = -3
y = -3(7)
y = -21
Can someone please help me it’s urgent
Answer:
8.5 in
Step-by-step explanation:
You are solving for the hypotenuse right? So you would use this formula:
c = square root a^2+b^2
the c is the hypotenuse (long side of a right triangle) and a will be 4 and b will be 7.5. substitute the numbers in, solve, and you get 8.5 inches!
x = square root 4^2 + 7.5^2
x = square root 16 + 56.25
x = square root 72.25
x = 8.5 inches

Write a equation to represent the hanger ,7th grade math help me
How many solutions
Line A: x + y = 2
Line B: 2x + y = 4
Answer:
1 solution (2, 0 )
Step-by-step explanation:
Given the 2 equations
x + y = 2 → (1)
2x + y = 4 → (2)
Subtract (1) from (2) term by term to eliminate y
2x - x + y - y = 4 - 2 , that is
x + 0 = 2
x = 2
Substitute x = 2 into either of the 2 equations and evaluate for y
Substituting into (1)
2 + y = 2 ( subtract 2 from both sides )
y = 0
one solution is (2, 0 )

Does a circle have a diameter of 7.6 feet which measurement is closest to the circumference of the circle in feet?
Answer:
23.864 ft
Step-by-step explanation:
circumference = pie x diameter
pie= 3.14
diameter= 7.6ft
therefore, circumference =
3.14 x 7.6 ft
=23.864 ft
roundoff to the nearest tens=23.9 ft
if A(2;2) and B(-3;4), determine the equation of AB, in the form y=mx+c
Answer:
[tex]y = -\frac{2}{5}x + \frac{14}{5}[/tex]
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
[tex]y = mx + c[/tex]
In which m is the slope and c is the y-intercept(value of y when x = 0).
A(2;2) and B(-3;4)
When we have two points, the slope is the change in y divided by the change in x. So
Change in y: 4 - 2 = 2
Change in x: -3 - 2 = -5
Slope: [tex]m = \frac{2}{-5} = -\frac{2}{5}[/tex]
So
[tex]y = -\frac{2}{5}x + c[/tex]
A(2;2)
When [tex]x = 2, y = 2[/tex]. We use this to find c.
[tex]y = -\frac{2}{5}x + c[/tex]
[tex]2 = -\frac{2}{5}(2) + c[/tex]
[tex]c = 2 + \frac{4}{5} = \frac{10}{5} + \frac{4}{5} = \frac{14}{5}[/tex]
So
[tex]y = -\frac{2}{5}x + \frac{14}{5}[/tex]
(51 + 62) + 14 = u + (62 + 14)
Answer:
u = 51
Step-by-step explanation:
(51 + 62) + 14 = u + (62 + 14)
(113) + 14 = u + (76)
127 = u + 76
=> Subtract 76 from each side of "="
51 = u
Hope this helps!
Answer:
u = 51
Step-by-step explanation:

Is it possible for a triangle to have a 54 degree angle and a 126 degree angle? Explain why or why not.
Answer:
No
Step-by-step explanation:
Those are only 2 angles and they already equal 180, Every single triangle has a sum of 180 and if you already hit 180 with only 2 out of the 3 points, it's not possible
Answer:
No
Step-by-step explanation:
No, because the 3 angles of a triangle have to add up to 180 degrees. The given 2 angles already add up to 180 degrees leaving no room for the missing angle.
can an obtuse triangle have a 90 degree angle?
Answer:
No
Step-by-step explanation:
Obtuse has an angle that is greater than 90 degrees. To be obtuse the angle must be 91 and up. Right triangles are 90-degree angles. Acute triangles have an angle that is less than 90. So, 89 and below.
I hope I answered your question correctly.

A large popcorn bag holds four times as much as a small popcorn bag. At the end of a party,
3 1/3 small bags and 2 1/4 large bags were left.
a) How many small bags would the leftover popcorn fill?
b) How many large bags would the leftover popcorn fill?
Please help me fast, also show all work and steps please:)
Answer:
A] 37 / 3 = 12 1/3 ; B] 37 / 12 = 3 1/12
Step-by-step explanation:
Let small popcorn bag hold = p units popcorn. So, large popcorn bag hold 4 times ie 4p units popcorn.
Left popcorn = 3 1/3 ie 10 / 3 small bags , & 2 1/4 ie 9 / 4 large bags.
So, total popcorn left = Sum( No. of popcorn in each bag x no of bags) = [ 10 p / 3 ] + [ (9 x 4) p / 4 ] = 10p / 3 + 9p = (10p + 27p) / 3 = 37p / 3
A] Small bags for left popcorn = Total left popcorn / Per small bag popcorn = ( 37p / 3 ) / (p) = 37 / 3 = 12 1/3
B] Large bags for left popcorn = Total left popcorn / Per large bag popcorn = ( 37p / 3 ) / (4p) = 37 / 12 = 3 1/12
The following are six observations collected from treatment 1, four observations collected from treatment 2, and five observations collected from treatment 3. Test the hypothesis at the 0.05 significance level that the tre atment means are equal.
a) state the null and the alternate hypotheses
b) What is the decision rulec).
c) Compute SST, SSE, and SS total
d) Complete an ANOVA table
e) State your decision regarding the null hypothesis
Treatment 1

Treatment 2
13, 20, 14, 13
Treatment 3

Answer:
Since the calculated value of F=0.20 does not fall in the critical region
F ≥ = 3.481 we reject the alternate hypothesis and accept the null hypothesis and conclude that there is no difference between the means of the 3 treatments.
Step-by-step explanation:
As the sample size are different we can run anova in the excel.
Part a)
The null and alternate hypotheses are
H0: μ1=μ2=μ 3 against the claim Ha: Not all three means are equal
The significance level ∝ is chosen to be 0.05
Part b)
The critical region is F≥ F(0.05,5,9) = 3.481
Part c) SST, SSE, and SS total
SS total= 144.933
SSE= 129.8333
SST= 15.1

10³x10³x10²
Answer:
100,000,000/10^8
Step-by-step explanation:
10^3 = 1000
10^3 = 1000
10^2 = 100
Therefore,
= (1000) x (1000) x (100)
= (100,000) x (100)
= 100,000,000
or
= 10^8

Solve for 42.
2 = [?]
44/62
Answer:
∠2 = 41°
Step-by-step explanation:
∠2 + 49° + 90° = 180°
∠2 + 139° = 180°
∠2 = 180° - 139°
∠2 = 41°
Answer:
[tex] \displaystyle \angle2 = \bigg[{41}^{ \circ} \bigg][/tex]
Step-by-step explanation:
we are given a right angle triangle
we want to figure out the missing interior angle
recall that,
one of angle measure of a right angle triangle is 90° interior angles of a triangle add up to 180°thus our equation is
[tex] \displaystyle {49}^{ \circ} + \angle2 + {90}^{ \circ} = {180}^{ \circ} [/tex]
simplify addition:
[tex] \displaystyle \angle2 + {139}^{ \circ} = {180}^{ \circ} [/tex]
cancel 139° from both sides:
[tex] \displaystyle \angle2 = {41}^{ \circ} [/tex]
hence,
the measure of the missing angle is 41°

Graph the system of Inequalities presented here on your own paper, then use your graph to answer the following questions:
y > 3x + 10
y<3/4x-1
Part A: Describe the graph of the system, including shading and the types of lines graphed. Provide a description of the solution area. (6 points)
Part B: Is the point (8, 10) Included in the solution area for the system? Justify your answer mathematically. (4 points)
(10 points)
Answer:
Step-by-step explanation:
Given the inequalities as
y>-2x+3
y<1/2x-2
Graph the inequalities on the graph tool
The solution is points in the shaded area such as (2,2),(4,4),(4,2),(2,-2),(2,-4)
The point (-2,3) is not included in the solution area because it is located in the un-shaded area.
Mathematically, taking points (-2,3) into the inequality
y>-2x+3
3>-2(-2) +3
3>4+3
3>7---------------------not correct because 3<7
how can we rewrite the slope formula,so that we have point-slope form
